NVX XMICROLOC2 2-kanalni linijski izlazni pretvarač - uputstvo za upotrebu

1. Uvod

The NVX XMICROLOC2 is a compact 2-channel line output converter designed to integrate aftermarket amplifiers with factory (OEM) car audio systems. It converts high-level speaker outputs from a factory head unit into low-level RCA signals, allowing for the addition of an amplifier. This device features an input circuit that corrects crossover distortion, individual adjustable outputs, and an auto turn-on function via DC offset, simplifying installation and ensuring optimal audio quality.

2. Sigurnosne informacije

Please read all instructions carefully before installation. Failure to follow these guidelines may result in damage to the product, vehicle, or personal injury.

• Always disconnect the vehicle's negative battery terminal before beginning any electrical installation.
• Ensure all wiring is properly routed and secured to prevent pinching, cutting, or short circuits.
• Use appropriate wire gauges for all connections.
• Ako niste sigurni u vezi s bilo kojim dijelom procesa instalacije, obratite se profesionalnom instalateru auto audio sistema.

5. Postavljanje i instalacija

The NVX XMICROLOC2 is designed for straightforward integration into existing car audio systems. Follow these steps for proper installation.

5.1 Ožičenje

The XMICROLOC2 connects to your factory speaker wires and provides RCA outputs for your amplifier, along with a remote turn-on signal.

1. Ulazno ožičenje: Connect the high-level speaker outputs from your factory head unit or amplifier to the corresponding input wires on the XMICROLOC2.
   • Identify the positive (+) and negative (-) wires for the left and right speaker channels.
   • Connect these to the XMICROLOC2's input wires. Refer to the wire color code (if provided on the device or packaging) for correct connections. Typically, these are twisted pairs.
2. RCA izlaz: Connect standard RCA cables from the XMICROLOC2's RCA outputs to the input of your aftermarket amplifier.

3. Daljinsko uključivanje: The XMICROLOC2 features an auto turn-on function via DC offset. This means it detects when the factory head unit is on and provides a 12-volt remote turn-on signal to your amplifier.
   • Connect the remote output wire from the XMICROLOC2 (usually a blue wire) to the remote turn-on input of your amplifier.
   • No separate remote wire from the head unit is typically needed for this feature to work.
4. Napajanje i uzemljenje: The XMICROLOC2 typically draws power directly from the speaker input signals and does not require a separate 12V power and ground connection for its operation, relying on the DC offset for turn-on. However, always verify the specific wiring instructions provided with the unit.

5.2 Podešavanje izlaznog nivoa

The XMICROLOC2 has individual adjustable outputs for the left and right channels. These adjustments are typically small potentiometers (screws) located on the unit, often labeled 'L' and 'R'.

1. Before making adjustments, set your amplifier's gain controls to their minimum (lowest) setting.
2. Play a familiar audio track at a moderate volume level on your factory head unit.
3. Using a small screwdriver, slowly turn the 'L' and 'R' adjustment screws clockwise on the XMICROLOC2 until you hear a clean, undistorted signal from your amplifier. Avoid turning them too high, as this can introduce distortion.
4. Once the XMICROLOC2 outputs are set, you can fine-tune the amplifier's gain controls to achieve the desired overall volume and balance.

5.3 Montaža

The compact design of the XMICROLOC2 allows for flexible mounting options. Choose a location that is dry, away from excessive heat, and easily accessible for adjustments if needed. Secure the unit using screws or double-sided tape (not included) to prevent movement.

6. Uputstvo za upotrebu

Once installed and adjusted, the NVX XMICROLOC2 operates automatically. When your factory head unit is turned on, the XMICROLOC2 will detect the DC offset from the speaker signals and activate the remote turn-on output for your amplifier. When the head unit is turned off, the remote turn-on signal will cease, and your amplifier will power down.

The primary operational aspect is the initial setting of the output levels. After the initial setup, no further user interaction is typically required unless you change your amplifier or head unit, or if you wish to re-balance the audio levels.

7. Održavanje

The NVX XMICROLOC2 requires minimal maintenance. Follow these guidelines to ensure longevity:

• Uređaj održavajte čistim i bez prašine i ostataka. Za čišćenje koristite meku, suhu krpu.
• Izbjegavajte izlaganje uređaja ekstremnim temperaturama ili direktnoj sunčevoj svjetlosti tokom dužeg perioda.
• Ensure all wiring connections remain secure. Periodically check for any loose connections.

8. Otkrivanje problema

If you encounter issues with your NVX XMICROLOC2, refer to the following common problems and solutions:

• Nema zvuka od Ampdizalica:
  • Check all wiring connections, especially the input speaker wires and RCA outputs.
  • Verify that the factory head unit is producing sound to the speaker inputs.
  • Osigurajte amplifier is receiving a remote turn-on signal from the XMICROLOC2. Check the amplifier's power indicator.
  • Potvrdite amplifier's gain settings are not at minimum.
• izobličeni zvuk:
  • Reduce the output level adjustments on the XMICROLOC2.
  • Reduce the gain settings on your amplifier.
  • Ensure the input signal from the factory head unit is not already distorted.
• Amplifier Does Not Turn On:
  • Verify that the factory head unit is powered on and playing audio. The XMICROLOC2 uses DC offset for turn-on.
  • Check the remote turn-on wire connection between the XMICROLOC2 and the amplifier.
  • Some factory head units may not produce sufficient DC offset on their speaker outputs. In rare cases, a separate remote turn-on wire from the vehicle's ignition might be required, bypassing the XMICROLOC2's auto turn-on feature.
• Zujanje ili buka:
  • Ensure all ground connections are secure and free from paint or corrosion.
  • Check for proper routing of RCA cables away from power wires to prevent interference.
  • Verify that the XMICROLOC2's output levels are not set too high, causing the amplifier to clip.
